Lambley Viaduct is a Grade ll* listed viaduct on the Haltwhistle to Alston railway which was closed in the 1970’s. The viaduct had been left to decay but eventually funds were found for its repair. Blackett-Ord Conservation were responsible as lead consultant for extensive repairs, complete repointing, the provision of new gates and a new staircase for access. The deck was relaid with new drainage to preserve the stone structure. The project won the RICS Conservation Award.
